Yesterday I saw a pic claiming to be of local law enforcement keeping the protestors separated from ICE. It was shared by protestors very upset that ICE was being kept safe while ICE shot at the protestors with tear gas — but(!) I have no way to tell if that was even taken this week in LA or 10 years ago in a different continent, because even before GenAI, there's loads of cases where people share videos of something awful, but label it about something completely different and use it as evidence about that other thing.
The person you replied to is looking for evidence that "local law enforcement did nothing to protect ICE from the mobs that try to set free illegals" — it's really hard to show "did nothing" from any single clip.
Even absent GenAI being pretty good now, what kind of video do you think will actually demonstrate that (1) local law enforcement, (2) did nothing, not just in the area being filmed but even when the camera was off, (3) specifically that the mobs were trying to set free "illegals" rather than being very unhappy that unidentified armed people wearing masks were hauling away their local pizza maker who they'd known for a decade?
